Application May 2l, 1940, Serial No. 336,473

1 Claim,

This invention relates to an insole, and it is a particular object of the invention to provide a device of this kind to be used by a person suffering from callous or corns on the under surface of the foot and when the metatarsal bones are unusually large.

Another object of the invention is to provide a device of this kind comprising a lamination conforming to the general contour of a foot together with flexible leaves secured to the under surface of the lamination to rbuild up the same as may be required to compensate for any abnormal. formation on the sole of the foot,

The invention consists in the details of construction and in the combination and arrangement of the several 'parts of my improved insole whereby certain important advantages are attained and the article rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order `that my invention may be the better understood, I will new proceed to describe the same with reference to the accompanying drawing, wherein: I

Figure 1 is a view in bottom pian of an insole constructed in accordance with an embodiment of my invention;

Figure 2 is a longitudinal sectional view taken substantially on the line 2--2 of Figure 1;

Figure -3 is a detailed transverse sectional View taken substantially on the line 3-3 of Figure 1.

As disclosed in the accompanying drawing, I denotes a sheet of material of soft leather or the like and which is of a contour to snugly fit within a shoe. At a desired distance inwardly of the toe end of the member I and closely adjacent to the forward part of the ball portion thereof is secured by a row 2 of stitching or the like the folds or plaits 3 which extend entirely across the member I. These folds or plaits 3 are disposed across the under face of the member I and are comprised in the inner end portion of a exihle leaf 4 of rubber or other preferred material of a contour closely conforming to the contour of the toe extremity of the member I.

As herein disclosed' the rear or folded end of this member 4 is straight and the bends of the folds' inner margin of the leaf 4 are the folded leaves' 5. As herein disclosed these leaves 5 are formed from a single length of material of proper dimensions with the forward ends of the folds feathered with the under fold outermost. These leaves 5 successively dier in length with the longest leaf at the bottom. These superimposed leaves 5, as herein disclosed, are secured to the` member I b-y the transverse row 6 of stitching and the undermost or longest leaf 5 .terminates at a.v point closely adjacent to the junction `between the heel and instep portions of the member Il. f

The forward edges of the leaves 5are spaced from the folds 3 a distance suflicient, and such spacing is so located, to accommodate any cal-v lous or corn there may be on the sole of the foot of a'person or such space may be solocated as to compensate for the forward extremities of the metatarsal bones and particularly when such bones are unusually large.

The leaves 5 at the outer side thereof are also vpreferably outwardly and rearwardly rounded,

as at 1, to increase the elciency of the insole.

It is believed to be obvious that with the use of my improved insole a person having callouses or corns on the sole of a foot or who may have metatarsal bones of abnormal size cany wear a shoe with decided comfort.

It is to be particularly pointed out that the line of the folds 3 transversely of the insole is on an angle with the. high or forward portion being at the inner side so that the folds or plaits 3 will extend a great-err distance under the big toe than under the little toe.

From the foregoing description it is thought to be obvious that an insole constructed in accordance with my invention is particularly well adapted for use by reason of the convenience 'and facility with which it may be assembled and used, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and i spirit thereof and for this reason Ido not Wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention i practice except as-hereinafter claimed.` 1

I claim:

An insole for a shoe comprising a member of flexible material to substantially snugly engage within the shoe from the toe end to the heel end thereof, and iiexible leaves secured to the under surface Vof the member at the toe portion and at the instep portion but at points spaced apart the opposed margins of the leaves being substantially straight and extendingV transversely across the member,

OLAF H. ANDERSEN.
